T0 all 1,071,071?, llt mfr/ 7j concern:

Be it known that l, THOMAS ROBERTS, a subject of the King oil Great Britain, and a resident of 38 Deane road, Bolton, in the county of Lancaster, England, have invented certain new and Improved Mechanism lor Filling Receptacles, ot' which the followingdescription, together with the accompanying sheets of drawings, is a specilication.

My invention relates to machines or mechanism for use in lilling bottles, jars, cans, canisters, or the like with liquid or semiliquid substances; and it consists in the construction of or the application of means to such machines or mechanism whereby the feeding of the liquid or semiliquid substances is arrested automatically by the making or breaking ot an electrical circuit when the desired quantity has been supplied to the bottle or other receptacle.

1n carrying my invention into eil'ect l make use of the devices constructed and arranged as hereinafter described and as illustrated by the accompanying drawings, in which- Figures l and 2 are front and side elevations, respectively, of a machine Afor 'lilling bottles, cans, or other receptacles having my improvements applied thereto. Figs. 3 and 4 are part-sectional front and side elevations, respectively, drawn to an enlarged scale, ot' portions of said machine hereinafter described. Figs. 5 and 6 are detail drawings of parts hereinat'ter referred to. Figs. 7 and 8 areront and side elevations, respectively, ot means tor use in filling collapsible tubes constructed in accordance with my said invention. Fig. 9 is a side elevation ot' a modilied form of my improved apparatus. Figs. lO and 1l are front and side elevations, respectively, showing a series of my improved devices mounted in proximity with each other.

Similar letters of reference indicate similar parts throughout the several views.

Figs. l and 2 illustrate a machine for filling bottles, jars, or the like in which the valvespindle a is raised to open the supply-valve, mounted within the casing a7, by means ot the 'foot-lever I), link slide b2, rod b3, and lever b". The valve-spindle a' is returned quickly to its seat by means of the spring b and the weight ol? the other parts connected to it. Said spindle is threaded, as shown, whereby the valve may be adiustably secured thereto. The receptacles c to be lilled with liquid 'from the tank A are placed upon the scale pan or plate c, the arm c2 of which is t'ulcrumed at c3 to the supports c", carried by the slide o2. Fixed to the support (l Within the slot d', in which operates the lever is an electromagnet (Z2, the armature Z3 ot' which is fulcrumed at d" to said support (I, while its other end, (Z5, (or a pin connected thereto,) is formed, as shown, so that it may be moved beneath or within an opening in the lever L", when the latter is in its raised position, by means otl the spring (.Zi'. Upon the stationary arm er of the weighing device is mounted the bracket e, which carries a contact-piece e', the latter being insulated 'from said bracket. VWires or conductors @2 e3 are connected to the bracket c and contact-piece c', respectively, and tothe terminals (Z7 tls, mounted on the casing d, which contains the electromagnet d. lt will thus be seen that an electrical circuit may be completed or closed when the arm c2 is in contact with the piece c', said circuit extending trem the battery or generator B, through the conductor c2, terminal (Z7, electromagnet d, terminal (ZS, conductor c, contact e, arm c?, and framework of the weighing device, through the arm c" and conductor e, to said battery B. By these means I am enabled to lill into each otl the tins or other receptacles c a predetermined quantity of liquid, the valve being opened by the toot-lever and held open by the armature (Z3 and lever 7)" until said quantity et liquid has been supplied, when by the descending' ot the scale-pan c' the arm ci is moved to complete the electrical eircuit and cause the armature (Z3 to withdraw its end Z5 from beneath said lever If and allow the latter to descend and close the valve. The quantity ot' liquid to be lilled into the receptacles c is adjusted or regulated by means ot' the sliding weight c,

ln Figs. 7 and 8 I have illustrated a device for filling collapsible tubes f. The valvespindle u/ is adj ustably connected to the armature of the electromagnet g', said spindle being threaded, as shown, said armature mov- IOO ing over the guides or supports g2. The valve a is held in its open position by the electromagnet g' and is closed when the circuit is broken by the spring a, The collapsible tube f is placed in the cup or receptacle f when being filled, and the latter is carried by the lever-arm f2, fulcrumed at f3 and provided with an adjustable weightf'i. In the drawings the valve a is shown as being open, and the electric circuit from the battery B is completed through the medium of the wire g3, terminal g4, electromagnet g', terminal g5, wire g, terminal g7, conductor gs, pillar 99, arm f2, post gli, conductor gw, -terminal gu, and conductor g1g. This circuit remains closed until the predetermined quantity of liquid has been received by the tube f, when the arm f2 oscillates and its end ,f5 comes into contact with the insulated part g1, thus breaking the circuit and allowing the valve a to be returned to its seat by the spring a6. The cup f is guided, so as to move vertically in order to keep the tube f in an upright position, by means of the lever-arm f 6, connected to said cup and to the pillar Q9.

Fig. 9 illustrates a device for delivering measured quantities of liquid into bottles or other receptacles by means of a vessel which is fulcrumed at 7; upon the support 702 and which moves on its said fulcrum when a certain predetermined quantity oi' liquid has been fed thereto to so cause said liquid to be passed into the bottle or other receptacle c, mounted on the adjustable support 08, (which may be raised and lowered by means of a foot-lever and counterweight,) through the medium of the funnel c. By means of the adjustable Weight 763, mounted on the arm 704, the amount of liquid desired to be fed to the vessel 7u in order to cause it to oscillate may be varied. The means for opening and closing the supply-valve are or may be similar to those illustrated by Figs. 7 and 8, so that during the time that the liquid is being fed to the vessel 7c the electrical circuit from the source B is completed through the conductor g, terminals gi and g5, electromagnet g, conductor f/G, terminal 71,'5, vessel 71", bearings 752, and conductor'lc.

In Figs. l0 and ell I have illustrated a series of devices for use in illing liquids, all of which are connected to one tank or receiver A. The Valves a, shown in these igures are especially applicable for the filling ofv paint or similar substances into cans c, and these latter are mounted upon weighing devices similar to those illustrated by Fig. l, the electrical circuit being completed and broken in a similar manner to that indicated by Figs. 7 and 8.

In the several drawings the nozzles through which the liquids pass to the bottles or receptacles are indicated by the letter a, and these may be'interchangeable as desired in accordance with the requirements of the varied liquids being filled.

The wires or conductors may be laid or fixed as desired, so as not to interfere in any way with the operations o't' the machine or attendant, while the source of electricity B may be a battery, dynamo, storage battery. or any suitable kind ot' generator.

The varied forms ot` mechanism shown and described maybe mounted upon su itableframework and the liquid to be filled led thereto by pipes or conductors, or they may be mounted upon supply-tanks A, as shown by the several iigures. Whenever convenient, the parts of mechanism are protected by guards or covers, as those marked 7" and s s.

Switches of any ordinary or well-known kind, as those marked qI q, Figs. l() and l1, may be employed in any of the varied devices to arrest the operations of the machines or mechanism when desired.

It will readily be seen that I may make use of my improved devices in connection with other forms of valves employed for filling liquids into receptacles, such as sliding or sluice valves and the like.

In devices wliere a long lift of the valve is required the armature or core of the magnet or solenoid may be raised by a hand or foot lever, the electrical circuit being broken and closed as hereinbetore described.

Instead of making use of electromagnets as above described I may, whenever desired, employ solenoids as shown at 1', Fig. 5, to attain the same results, and in the arrangement illustrated by the said Fig. '5 I employ the spring el to act upon the end Z5 of the lever carrying the core of the solenoid in a manner similar to that shown in Fig. 3.
